Snakebites in Pediatric Patients in Kahramanmaraş: Is Pro-brain Natriuretic Peptide a Prognostic Biomarker for Snakebites?

Abstract

Background: Snake envenomations are a serious cause of mortality and morbidity in the world.

Aims: This study was conducted to investigate snake bites in pediatric patients in Kahramanmaraş and to determine whether pro-brain natriuretic peptide (proBNP) has a prognostic value in these patients.

Methods: Pediatric patients aged <18 years who presented to the pediatric emergency department with snakebites were reviewed retrospectively. The demographical, clinical, laboratory, treatments, and outcomes data were collected from their medical records. Stage 0 and 1 envenomation was considered as a non-serious complication and stage 2 and 3 envenomation was considered as a serious complication.

Results: A total of 32 pediatric patients, six females and 26 males, between 2016 and 2021, were included in the study. The mean age was 12.52±3.28 years. There were seven patients without serious complications and 25 patients with serious complications. The best cutoff point for proBNP to predict serious complications was found to be ≥272.5 ng∙L^-1 (sensitivity, 83.3%; specificity, 100%, p=0.011). We also detected complex regional pain syndrome in one of our patients.

Conclusions: In this study, proBNP was shown to be predictive of a poor outcome of snakebites. Moreover, complex regional pain syndrome, which is rarely reported in the literature, should be kept in mind during the long-term follow-up of snakebites.
